Specification of Letters Patent.

1 Application filed February 27, 1920. Serial r cemes.-

Toallwhomitmayconcem." H Be it known that we, PAUL H. GARTNER and JOHN H. GAR'rNnR, citizens of the I United States, and. residents of Lava Hot Springs, county of Banno'ck, and State of, Idaho, have inventedcertain new and use-,

ful Improvements in Work and Display.

Stands, of which the-following isaspecification; i I It is well appreciated that it is often desirable, in connection with the display and selling of automotive vehicles, to show a prospective purchaser of such vehicles certain details of'construction which are" only visible from the under side of the same.

,In connection with having accessto the to assume a reclining'position to be enabled to view certain points of construction on the under side of the car and hence it must be left to the imagination of the purchaser and the descriptive powers of the salesman to permit the former to conceive the points brought out by the latter; V

In connection with:repair work it has heretofore been proposed that a mechanic recline upon what is known as a walker, in other words, a small platform upon casters, and by means of the latter to move thesame and his body to positions under the vehicle from which the parts to be worked upon would be accessible. .Where this mode of repairing has not been resorted to a pit has been provided in which the mechanic works, the vehiclebeing passed over the same. In view of the fact that the mechanic must always look upward; and work with his hands over his headg-an unnatural position-the -work proceeds p but 7 slowly andthe .mechanic, in both cases, is

subjected T to great physical fatigue as well the most practicalrm'ethodrof overcoming the being operated so as tolrender the under slde of the vehicle-readily accessible,

With this end in view,-stands have been proposed-having-this object in .mind, but these stands have proven for the most partimpractical in that'they were \not of sufii- Patented ug. 9, 19 2 1 ciently rugged construction to permit of thelr being sub ected to the rough usage and 4 strains whichv they would necessarily have to undergo, and where they have been suf-' ficiently strongtowithstand unlimited usage in this respect these stands havebeen, for the most part, inaccessible to the usual small caragent or garage owner in that their cost hasbeen prohibitive.

With the above in mind we have constructed arstand whichisrcapable of grasp- 111g and retaining any type ofautomotive vehicle and by means 'of which said vehicle may be moved readily to a position in which its under side will be easily accessible for repairing or display purposes, and which is so simple 1n construction and operation as to be capable of being manufactured at an.

extremely low price, permitting its pur chase by virtually anyonehaving need of the same;

7 Reference is had to the attached sheet oif q drawings which illustrates one practical embodlment of our invention, and in which-.-

" Figure 1. is a rear view of our improved type of stand,- showing an automotive vehicle, partly in section, positioned thereon;

Fig, 2. is a partly sectional side viewof the same,. and I 1 Fig. 3.illustrates a detail of the operating mechanism. 1 1

In these views like reference numerals designate similar' parts and the reference numeral 5 indicates base members of any suitable construction upon which are mountedopposed spaced angle irons 6, which irons run longitudinally with respect to the" base portions 5 v At any desirabletpoint in thelength I of the irons 6, pivot pins 7 are provided,;which pins serve to retain andact as vpivots for channel irons 8, forming bell cranks. t

- Further channel irons, or other suitable members 9,- extendtransversely to the mem any desirable means such as-turn buckles 1 1,

site ends retaining the vehicle by virtue of the fact that these latter ends are forked,

comprising a prong 12, adapted to lie flush against the face of the channel iron forming. the frame of the vehicle, the second prong thereof being hook-shaped and having its end extending into the channel of said frame.

hooked prongs 12 and 13, respectively, of the turn buckles 11, in their proper position,

any suitable means such'as a bolt and nut" construction 14, may be used. Now to provide means permitting of a tilting on the part of the bell cranks, formed; by the channel irons 8, around'their respective pivoting pins 7, a rotatable shaft15 is mounted adjacent to the ends of the angle irons 6, and drums 16are secured to such shaft preferably at points between pairs of irons forming a unit;

Any suitable meansfor rotating and hold ing such shaft may be provided such as a hand crank 17 which may be held by means of an interlocking pin 18; The hand crank 17 serves to rotate a small gear 19, meshing with a train of'redu'ction gears or a single gear 20, coupled directly with shaft 15.

Secured adjacent the outer ends of the channel member 8 are one end of each of the cables 21, which extend thence to their re ber of turns around the same, extend betion upon the latter.

tween the angle irons 6 to a point adjacent the ends of the same, at, which point they pass over a pulley such as "22, their ends being secured asat 23, to the upper ends of the channel members From the foregoing it will be seen that it will be anextremely simple operation for a mechanic to move a vehicle upon the channel members 9 serving as rails, using any suitable means as an approach to such rails suclf as inclined channel members 25 having their outer ends in contact with the supporting medium,their upperends connected'with the channel members 9, thus permitting the vehicle to be readily moved to a desirable posi- The turn buckles 11 are now actuated so that their lower ends firmly grip the channel members 9, their forked, ends being applied and secured tothe frame of the ave-Y hicle 10 in the manner afore-described,ithe turn buckles 11 then being actuated so asf to the vehicle in a pull being exerted upon the "cables 21.

causing-a rocking of the channel members8 around their pivots 7, but by virtue of the readily accessible position. v V I a It will be noted from the construction emexerted upon such irons and prevent a falling of the bell cranks carrying the vehicle after the'latter has been moved to a point beyond its center of gravity. By means of this construction the vehicle may be held at any desired angle upon the pin 18 being reinserted to prevent the turning of the crank 17, but the tilting operation is usually con 7 With a view of holding the straight and tinued untilthe channel members 8 have swung through" a 90 are, at which latter point the underside of the vehicle is in a bodied in t'hed'rawingspin this application that we have provided a stand whichshall be extremely simple in construction and economical inthe manufacture of its parts andassemblage of same. In this connection it is to be noted that the angle'iro'ns Gserve as a bearingfortheshaft of the/hand crank 17,, the drum carrying shaft 15' and, actalso as a supportffor the pins 7, and retain the pulleys 22in applied position. I

From the foregoing description it will be seen that means of our improved construc tion that-thecable 21 extending between the angle i ons-e. and longitudinally thereof, travels in as-nearly a direct line as 1s possible, thus eliminating all undue. friction and permitting of an easy operation of the parts. Obviously modifications of structure might be resorted to without departing from the scope of our claims,'-which read lVe-cl-aim-i 1. A work stand including. aplurality of rockinglymounted bell cranks, one of. the

arms of each of, saidbell cranks restingin a normallyhorizontal plane,'means for engaging the opposite armsof'said bellcranks for rocking the same, rails extending'between.

said horizontally disposed arms, and means attached to said rails for retaining a vehi extending transversely of such separate arms, means for rocking saidarms and turn buckles having one .of'their ends engaging such rails, their upper end being forked, one

of the prongs of V such forked end being adapted to lie flush with thes'ide of the channel arms of theframe of, the vehicle placed upo'nsuch rails the second prong being hooked in shape and projecting into the channel"'of the frame of such vehicle.
